Javascript Array removeElement(element)

Array.prototype.removeElement = function(element) {
 var idx = this.indexOf(element);

 if (idx <= (-1)) {
  return;//w ww  . ja  v a 2 s .c  o  m
 }

};


Array.prototype.remove = function(from, to) {
 var rest = this.slice((to || from) + 1 || this.length);
 this.length = from < 0 ? this.length + from : from;

Problem 2. Remove elements

Write a function that removes all elements with a given value.
Attach it to the array type.
